ExtremeWare XOS 11.5 Command Reference Guide
601
configure sflow sample-rate
configure sflow sample-rate <number>
Description
Configures the sFlow default sampling rate.
Syntax Description
Default
The default number is 8192.
Usage Guidelines
This command configures the default sampling rate. This is the rate that newly enabled sFlow ports will
have their sample rate set to. Changing this rate will not affect currently enabled sFlow ports. The rate
is rounded off to the next power of two, so if 400 is specified, the sample rate is configured as 512. The
valid range is 1 to 536870912.
Configuring a lower number for the sample rate means that more samples will be taken, increasing the
load on the switch. Do not configure the sample rate to a number lower than the default unless you are
sure that the traffic rate on the source is low.
Summit X450a and X450e Series Switch and BlackDiamond 8800 a-Series and e-Series Modules Only.
The
minimum rate that these platforms sample is 1 out of every 256 packets. If you configure a rate to be
less than 256, the switch automatically rounds up the sample rate to 256.
Example
The following command sets the sample rate to one packet out of every 16384:
configure sflow sample-rate 16384
